Throughout the several views of the drawings similar referencecharacters are employed to denote the sameor similar parts. y

The er'nllvodirnent of the invention as illustrated ln Figs. l, 2 and 3comprises a single blank comeach hingedly connect to the said panel 58corner paratively greater in dimension in one direction j than in theother suitably scored to provide the desired carton supporting a basepanel and side Wall panels together with the panels for formingorproviding the lid. The blank is provided with a panel 25 which forms thebase or bottom of the carton and. has its bounding edges dened by scoreor fold lines 25, 21, 28 and 29. The score or fold lines 21 and 29,since they are longer than the remaining score or fold lines, constitutethe sides of the base 25 and have respectively, integrally, hingedly,Vconnected therewith extensions 39 and 3|. The extension 39 forms in theerected carton the side or front wall while the extension 3| in theerected carton forms the side or back wall together With a lid or coverwhich is hingedly connected to the said wall.

The blank extension 3B is divided by longitudinal score or fold lines32, 33 and 34 into a plurality of panels 35, 36, 31 and 38 between theattaching score or fold line 21 and the end of the extension 38. In theerected carton the panel 35 constitutes the side or front wall outerwall member and has its opposite ends dened by a score or fold line 39which are respectively substantially aligned with the carton bottom orbase panel end scores 26 and 28. The panel 35v through its end scores 39has hingedly connected to its opposite ends corner'pieces 40 Which aredesignated in the trade as bellows' corner pieces, and they are,therefore, each provided with a diagonal fold line 4|. The panel 36 inthe erected carton forms the side or iront walltop wall member and hasits end formed by cut lines 42 which like the score or fold lines 39 arerespectively in alignment With the carton base or bottom panel endscores 26 and 28. In the erected carton therpanel 31 constitutes theside or front wall inner Wall member having its ends dened by a similar`score or fold line 43 which respectively hingedly connects with theends of the panel 31 tucking naps 44.L Each or the tuck# ing iaps 44 islongitudinally divided by a score or fold line 45 for integrallyhingedly connecting thereto spacer flap V46 whichin the erected cartonunderlies the end wall for a purpose later to bemade clear. The panel 31is further provided, within its borders and near its end scores 43, withelongated apertures 41 that cooperate with the end wall panels forlocking the carton walls in erected positions as will later be madeclear. The remaining panel 38 has its ends defined by cut lines 43 andis slightly shorter than thepanels 35, 36 and 31 and in the erectedcarton constitutes a glue flap for securing the inner wall member 31 ofthe side or front Wall to the base or bottom panel 25. In o-rder toaccomplish this,

the carton base or bottom panel is provided with adhesive 48 on whichthe glue flap 38 restsas will later bemade clear.

The blank extension 3| includes the same panels as the extension 30 plusseveral additional panels to form a lid or cover for the box or cartonand which lid or cover is hollow as will later be made clear.Specifically, the extension 3| is provided with parallel score or foldlines 49, D, 5|,l 52, 53, 54, 55, 56 and 51 which form between them andthe'bottom or base panel scoreV or fold line 29 and the end of theextension 3| panels 58, 59, 60, 6|, 62, 63, 64, 65, 66 and 61. In theerected carpieces 4|! and form, what is known in the trade, bellowscorners each provided with a diagonal score or fold line 10. In theerected carton the panel 59 constitutes the box or carton cover paneland has its ends dened by score or fold lines 1I whichv are respectivelyin alignment with the score or fold lines 2B and 28 of the carton baseor bottom panel 25 and the said panel 59 is of substantially the samearea as the carton base or bottom 25. The vscore or fold lines 1| eachintegrally, hingedly, connect with the 'cover panel naps 12 which areadapted to be folded onto the panel 59 as shown in phantom lines at 13.The flaps 12 form aiinis'hed edge for the lid or cover as will beobvious from Fig. 3 with a portion of said naps forming a cover flangeas will later be made clear. In order that the flaps 12 may eiiicientlyfunction their ends are biased with a portion considerably shorter thanthe parallel dimension of the panel 59 so that it may underlie the innerspaced panel of the cover or lid; The panel 6|] is adapted to overliethe panel 59 along a zone inwardly of the score or fold line 59 and saidpanel 60 is of a Width substantially equal to the width of the top Wallmember and the panel 69 acts as a ange for the lid or cover to engagesaid top wall member. The panel 62 forms the cover or lid inner memberand is shorter in length and narrower in width than the main cover panel59 by so much as constitutes the side and end Walls top wall members.The panel 52 has its ends defined by score or fold lines 14 whichhingedly connect to the panel 62 closure ends 15 which are of a Widthequal t0 the spacing of the cover or lid and outer panels 59 and 62 fromone another. The panels 6| and 63 which are adjacent to and extendlongitudinally of the panel B2 are of a Width substantially equal to thewidth of panels 15 andcooperate therewith in eiecting the spacing of thepanels 59 and 62 from one another. In order to maintain these panels inproper spaced relation the panels 6|l and 63 have their endsrespectively defined by score or fold lines 15 and 16 and which score orfold lines respectively hingedly connect to the ends of their respectivepanels bendable flaps 11 and 18 that are disposed transversely of thetheir assembled positions each of the spacer i'laps or panels 15 has itsouter edge dened by a score or fold line 19 through which thereisintegrally hingedly attached thereto a tucking flap 89.

In the erected carton the flap 64 is adapted to overlie thercover panel59 along aA zone inwardly of the score or fold line 49 and, similar tothe pane1'60 form a flange for the cover or lid for engagement with thetop wall member of the carton side or front wall. In order to secure theflange panel 64 in position, adhesive 8| is applied to the panel 59inwardly of the score or fold line 49 and similarly in order tosecurethe panel 6D to the panel 59 the latterV to;-the.paneli36 ofthe blankextension 30`and forms thev carton side wall or. back .topdwall 44memberand has itsendsdenedby cut. lines 83 .which arelin substantialalignment;y with .the carton b-ase or bottom .panel end. scoresrr26 and28; Thexpanelv 66uin the erected carton. forms the side wall vor-backinner wall member in opposition tothe side wall or front inner wallmember 31. Therends ofy the kpanel66` are; deiined byf'score orkfoldlines 84 whichintegrally hirigedlyconnectto the endsof saidipanel66tucking flaps.85..which are similar to theztucking aps 44 of the frontinner: wallmembers. Eachtucking flapv 85 has hingedly` connectedtherewith .througha scoreor fold line 86 a spacer flap .81 which likethe spacer flaps 46 cooperate with the end wallsin formingv they sameand retaining them in erected positions as will later be made clear. iTheilap 6 6 is vfnrtherprovided within'l its border andnearits ends withelongated apertures88 that cooperatewith the end walls in retainingthemin position. The remaining flapyll, similar to the flap 38, formsthe means for. securing the inner wall member to the carton base orbottom panel 25 and constitutesa glue flap for which purpose it may haveapplied thereto adhesive 8 9 to engage the carton base or bottom panel25 along a. zone inwardly of its score or vfold line 29 corresponding tothe width of thetop wall member. It will be' understood that theadhesive 89 may be applied to the carton base or bottompanel instead ofto the flap 61 as; was pointed out` above in connection with theadhesive 48.

-Thecarton base or, bottom panell 25has integrallyhingedly connected toits ends through score or-,fold lines 26 and 28 end walls formingextensions` 90 and; 9| 'which` are; substantially identical withoneanother, and it is deemed su'- cient if but oneofthem. be -describedindetail. y Accordingly, extension 90 is provided between the score orfold line 26 and the outer end thereof with a pluralityof parallel scoreorv fold lines 92, 93, and 94 thereby providingv panels 95,96, S11-and98. In the erected-carton the panel 95 formsfvthehend wall outer wallmemberiandqhas its ends denedby score or fold lines 99 and |00.` Thescore or fold line 99 hingedly-connects tothe panel 9,5 thebellowscorner piece 4 0 while the-score or foldflineI hngedly connects -to thepanel-95 the bellows corner piece ,69:U The panel 96 in the erectedAcarton, forms the end walltop wall member while the panel 91 forms the.end wall inner wall member. Sincethe end wall. inner wallj member 91 isto be disposed between the carton front and backs inner wall members, ithastaflengthA shorter thanthe end Wall outer wall-member orpanel 95 Aby.so much as'rthexsaid'front and'back inner wall membersare-inwardlyspaced from the side edges of the cartonzbase orbottom-.25.` The said end'wall inner. Wall member or panel 91 has itsends, for a.major;portion thereof defined by score or fold lines|0|,whichhingedlyconnect to the ends ofthe saidapanel 91Vertica1 spacingflaps |02. Thefpanelil beyond `the spacing flaps `|02 has projectingltherefromlocking lugs |03 whichc operate with the front and `back innerwall members-,elongated apertures 41 and 88 in locking thefcarton wallsinftheir erectedv positions as will later be made clear.Theremainingpanel 98 of the :end wall extension Vconstitutes a.Slltlceivilap andgevenies: fthe? carton; base or. battom granel.

between the saidend .wall inner Vand Y outer`wall members to preventcollapse of said inner wall member. l

After the blank. has beencut and scoredfas above described andillustrated in` Fig. 1, it has applied thereto the adhesive 8| and82 aswellas the adhesive 89k to the panel 61l and similarL adhesive (48') tothepanelor glue nap 38. The side or front wall extension is then foldedon the score orfold line 32 for bringing the glue ap38 into contact withthe base or `bottom panel 25. The extension on. 3| is now folded 0n thescore or fold line 50A for bringing the panel 60 into engagement. withthe adhesive 82 whereupon the said extension isvreversely folded on thescore or fold line 5| to be again reversely folded on the score or foldline 52 thereby bringing the panel 64 vinto engagement'with the adhesive8|. At the same time the glue flap 61 with its adhesive 89 is broughtinto engagement with the base or bottom panel 25 along the zone inwardlyof the fold line 29 for securing the back wall inner Wall member orpanel 66, through the glue flap or panel 51 to the said carton base orbottom panel 25. The blank is now yin the position illustrated in Fig. 2and it is in thisposition that the carton is shipped to the user in itsvknock-down condition to be erected by the user.

The user upon desiring to place merchandise inthe carton either sets upthe carton Yproper or the lid in sequential order, and assuming that thecarton is to be set up first, the extensions 30 and 3| are actuated fromtheir knocked-down or flat position thereby effecting the upstandingofthe front and backwallsinner and outer wall members to be parallel toone-another joined at their upper ends by the-said front and back walltop wall members which are parallel with` the bottom or base 25, of. thecarton, as clearly i1- lustrated in Fig. 3. The tucking apsv 85 and 86are then arranged to be transversely of the carton base or bottom 25whereuponthe end Wall extensions and 9| are lifted from their flatposition to be vertically disposed to the base or bottom panel 25. Thepositioning ofthe. said'end wall extensions automatically causes thebellows'corners' 40: and `|59 respectively'to fold onv their diagonalfold lines 4| andk 10 and to be transversely-of'the said carton bottomvor. base 25. The spacer flaps 81 are then folded tooverlie thecartonbottom25 whereupon the panels 96, 91 and 98 are eachiolded'to beat right anglesto one another after folding or positioning the spacerflaps |02 to be normalv to thev panel91. The folding of thegpanels 96,91and 98 as just described automatically folds. the same inwardly olf the.carton proper and enclosing Within said panels the tucking flaps 85 andthe bellows corner ilaps 40 and 69. a

The carton is now reads7 ,to have itscover or lid erected which consistsin swinging Ythe inner panel 62A from its `flatsuperimposed positiononthe'main cover panel 59' to a position spaced therefrom, but paralleltherewithaas determined bygthe panels y6| and 63. At this time therflaps12 -arey respectively folded on the score or fold lines 1| to besuperimposed on thepanel 59 with the-ends of said naps 12.beneath thecover inner panel 62.v The cover foldable flaps 11 and 18 arenowpositioned transversely of the cover panel 59 whereupon the tuckingiiaps 80 are bent te be normal to the spacer flaps 15 and the; tuckingflaps 80inserted betweenthe cover panels 59 and 62gfor thereby lock-ingthe cover vin position 1t-inthe inner: Panel 62,: 0f. the. lid for cover1in? l7 wardly spaced from the cover main or outer panel 59.

The carton is now fully erected or set up as shown in cross section inFig. 3 and comprises a box or carton proper having hingedly connected toone of its side walls, or its back wall, a lid r cover which is inreality a separate compartment with a flange extending therearound toengage the top wall members of the carton front, back and end walls. Thecompartment of the cover may be utilized-to receive merchandise ormaterial capable of being saturated with a scent giving liquid such asperfume or the like and for which purpose the said panel 62 of the coveror lid may be provided with apertures |04 t0 permit the said pleasingodors to enter the ybox or carton proper when the lid is closed. Thesaid lid or cover compartment may further contain material adapted tohold liquid for supplying moisture to the box or cover or an insulatingmaterial such as disclosed in applicants above identified pendingapplication and which material is indicated in the drawings by thereference numeral |05. It will be appreciated that this inner panel ofthe cover or lid may merely act as a compressor or retainer to engagemerchandise within the box or carton proper or it may even have a cutout similar to the aperture |04 to embrace a portion of the contents ormerchandise of the box or cai ton proper. It should further be notedthat while the anges 60 and 83 are illustrated and have been describedas of a width substantially equal to the width of the front back and endwall top wall members they may be of a greater dimension which shouldresult in a compartment that was of an area less than the interior ofthe carton or box proper, or a cover or lid having a flange thatprojects beyond the box or carton.

The form of the invention illustrated in Figs. 4, 5, 6, and 7contemplates the use of a cover or lid that is without a compartment andformed from a blank separate from the blank of the box or carton proper.

It is believed that a description of the blank of Fig. 4 is unnecessarysince it involves the same elements as the blank of Fig. 1 except thatthe panels 59, 60, 6|, 62, 63 and 64 have been eliminated and the scoreor fold lines 55 and 49 consolidated as a. single score or fold linecarrying the reference character y49 in Fig. 4. The blank of Fig. 4 isslightly modified over that of Fig. 1 to the extent of providing in theside or front Wall top wall member elongated slits |06 and in providingin the back Wall top wall member 65, similar elongated slits |07. Theseslits act as receiving or attaching apertures for hinge lugs from thecover or lid to be subsequentially described.

The blank of Fig. 4 after being cut and scored has adhesive applied tothe glue flaps 38 and 89 whereupon the'side wall extensions arerespectively folded on their respective fold lines 32 and 49 to bringthe said glue naps into engagement with the box or carton base panel 25.The blank is then in the knocked-down condition as illustrated in Fig.and it is in this condition it is shipped to the user.

The cover or lid, as illustrated in the drawings, is of two sectionswith each section being respectively carried by one of the side wallsbut it is to be understood that a single cover may be provided forattachment to only one side wall. In either case the cover is formed ofa blank substantially centrally longitudinally Vdivided by a score orfold line |08- thereby provided .in the cover -panels |09 and H0.Projecting from one of the panels, panel H0 for example, is a pair ofhinge lugs IH and H2 each substantially T-shaped in plan and having astem portion H3 integrally, hingedly connected with the panel H0 througha. score or fold line H4 and each hinge lug having laterally projectingarms H5 and H6 each hingedly connected through a score or fold line andwith the stem IH. After the cover or lid blank has been formed asillustrated in Fig. 7, it is folded along the score or fold line |08 forbringing thepanels |09,v

and ||0 into face contact with one another and in which position theyare adhesively joined and shipped to the user.

The user sets up the box or carton of Figs. 4 and 5 in the same manneras above described with 'respect to the `box or carton proper of Fig. 1whereupon the arms H5 and H6 of each hinge lug H I and H2 are folded tolie on its hinge lug stern H4 whereupon the lugs are inserted throughthe hinge attaching slits |06 and |01 of the carton proper. The arms H5and HS after being inserted through the slits |06 and |01 outwardlyspring to their normal position to underlie the carton side walls topwall members for thereby attaching the said cover or lid to the cartonagainst inadvertent displacement.

Due to the fact that the side walls are hollow, the hinge lugs mayoscillate therein upon closing and opening of the lid or cover withoutrequiring bending in said lugs particularly if the said cover or lid isnot actuated beyond from its closed position when the said hingereceiving slits |06 and |07 are formed at the inner edge of the top wallmembers.

In the form of the invention illustrated in Figs. 8 to 1l, inclusive,use is again made of a hollow cover or lid with said cover or liddivided with one portion thereof carried by each of the side walls orthe front and back walls. The blank for forming this carton issubstantially identical with that of Fig. l except that the panel 59' inthe blank extension 3|' is but half of the width of that shown inFig. 1. Furthermore, the blank extension 3| has eliminated from it thepanel 60 which forms the flange at the free end of the cover. Otherwisethe extension 3|' of Fig. 8 is substantially identical with that of Fig.1.

The blank of Fig. 8 is modified in its side wall extension 30 to theextent of having the necessary cover panel therein to form a partialcover in the same manner that the extension 3| formed, Accordingly, theblank extension 30 of Fig. V8 has hingedly connected with the panel orside wall outer wall member 35, a panel l 8 which corresponds to thepanel 59' in the extension 3|. The panel H8 through a hinge or fold lineH9 has integrally hingedly connected therewith a panel |20 whichl inturn has integrally hingedly connected therewith through the score orfold line |2I a panel |22 that forms the lid or cover inner panel andcorresponds with the panel 62 of extension 3|. The panel |22 hasconnected with it through the score or fold line |23 a panel |24 thatinturn is connected through a score or fold line |25 with the panel |26connected with the side wall or front wall top wall member or panel 36through a score or fold line |21.

The ends of the panels H8, |20, |22, |24 and |26 are dened and carry thesame additional material as the panels 59', 60, 62', 63 and 64 of theblank extension 3|.

After the blank of Fig. 8 has been cut and scored as above described andas illustrated in agent.'v4.5'n

Fig; 8 :adhesive is applied ato fthen glue flapor panels 38 and 39 orthe adhesiveisl applied tothe box or carton main panel or .base'25 Iandadhesive is similarly Vapplied to the panels 64 and |26 or tothe panels59 and I8 inwardlyof their respective adjacent score or fold lines 49and 32 whereupon the blank extensions 39 Vand 3|' are folded on theirscore or fold lines |2I, and 5| thereby adhesively securing .the partsto one another in `a knocked-down `position as illustrated infcrosssection in Fig.`9. It is in this condition that the blank of Fig. 8 isforwarded to the user to be set up as illustrated vin Fig. 10.- l

.In order for the user to setup orerect the cartonfrom Fig. 8, hefollows the Vsame-steps as abovedescribed inthe setting up of the cartonof4 Fig. 1, except that he must open'both lids'or cover sections afterthe walls of the carton proper are-erected. The set up box or carton ofFig. '10 comprises a lid or cover section hingedly connected'with eachof the side walls, or the `front and `back of the carton, and may beactuated to a closed position with the free edges of the cover sectionsin engagementk with one another and `which free edges are formed by thepanel 60 `of extension 3|" and panel |20 of extension 3D". vIt will benoted that the lid or coversections of Fig. 10 are each provided withend flanges which engage the top wall members 96 of the end wallsinvlimitingV the `closing ofthe said cover sections, and which closedposition of one ofthe cover sections is illustrated in Fig. 11. The formof the invention illustrated in Figs. 12 to 15, inclusive, issubstantially identical with that illustrated in Fig. lexceptthat one ofthe cover sections is provided with la flange at its free end adapted torest on topof the other Alid or `cover section which is not providedwith said longitudinal flange. In order to provide this structure theblank extension 3| of Fig. 2 has its cover or panel section 59" slightlywider than the corresponding cover `section vpanel 59' of Fig. 8, alsothe blank extension 3|" has hingedly'connected to the cover sectionpanel 59" thexpanel 60 of Fig. 1 which was eliminated from the extension3| of Fig. 8. f

. After the blank of Fig. 12 has' been cut' and scored as abovedescribedand illustrated, 'it has theyadhesive applied .thereto and isfolded in substantially the same'manner as Fig. 2 in so far as its blankextension 30 is concerned while the extension 3| of Fig. 12 is foldedinthe same manner as the extension 3U of Fig. 8 vand isso shipped to theuser. Theuser'goes through the same steps in erecting the carton of Fig.14 from the blank of Figs."12 and 13 asv described inconnection witherecting the blank of Figs. 1 v'and 8." The resulting carton'from theblank of Fig. 1 is as illustrated in Figs. 14 'and 15 with one of thesections having longitudinal flanges projecting from the free endthereof which overlapped the adjacent free end of the other coversection all as clearly discernable from Fig. 14 and clearly illustratedin Fig., 15. lBy this construction there is provided a box'or cartonwhich may havethe cover providing a somewhat sturdier construction sincethe flange of the one lid or cover section iirmly engages the top of thesecond'lid or cover section. v'In the embodiment of the inventionillustrated in Figs. v1B to 19, inclusive, a `construction is utilizedwhich is substantially `thereversefofthe construction shown in Fig. V8,Ain that the-side and end Y wall members which lare integrally, hingedlyconnected with the'base o r bottom panel 25forms'the `innerwallfmembers'instead of the outer wallimembers. Byrthis 'constructionitis possible Vto have the'same sideof the board exposed instead ofhaving the yoppositesidesthereof exposed a's is the 'case with theconstructions heretoforedescribed. In other words,`and as illustrated inFig. 18,' the `inner wall member of each ofthe ,-four sides Vis integraland continuous upwardlyfrom thesaid base or bottompanel and thesaidWalls thereby are folded'outwardly of the carton proper insteadfofinwardly. This l construction is particularly advantageous `when itisdesired to print orotherwise decorate both the inside and outside of thelid or cover,and/ or .the inside and outsidevoi:` the carton walls, andthe inside` of the base or carton bottom. In other words, the blank asillustrated in Fig. 16 shows the unfinishedv side uppermost and it willbereadily understood that by. turning the blank torest on its wrong sideall exposed surfaces, when the carton or package is in use, can beprinted,` lithographed, or otherwise decorated in one operation`whereupon the carton may be securedin its knock-down position byfolding the side wall extensions on themselves to bring the glue'flaps38 and 89 into engagement with the carton base or bottom panel 25 and toAbring the coverrhinge or spacing panels 64 and |26 into engagement withthe cover sections outerpanels for completing the knocked-downcarton-for shipment Vto the ultimate user. The erection of the blankofFig. 16 fromits knock-down posi-` tion in Fig. 1'7 to itserectedpostionof Fig.r 18 follows substantially the same steps as abovedescribed, namely, the setting up of the side walls followed by thesetting up ofthe end walls which encloses the bellows corners andthe'side walls tucking flaps whereupon' the lid or cover sections areset up as above described.

It should b'e noted thatr in the specific embodiment in Figs. 16, to' 19the walls are locked in 'their'e'rected position slightly differentlyfrom the locking of the erected walls as lpreviously described. j Thesaid end-wall instead of having locking llugs projecting therefromV areprovided withy largeraps orpanels |28'which takes the place of [thespacerflans 98 and are `utilized as the locking means. The sidewallsglue flaps 38Y and 61 have .the adhesive thereof stormedr short of theirends as at |29 -therebvproviding a free portion which cooperates withthe base or bottom Apanel 25 to receive the locking lugs |28 as clearlyillustrated in Fig. 19 jand said locking portion yof the .glue flaps 38andV 61 indicated by the reference numeral |30.

In connection with Figs. 18 and 19 there is illustrated the .use of aplatform |31 spaced from the carton bottom 25 by spacers |32 integralwith and depending from the platform edges. By this constructionan airspace |33 is provided' above the said carton base 25.

From the foregoing it is believed Anow evident thatv there has beenprovided a carton or packagev of the hollow wall type having secured tothe upper -end 'of one or both walls a cover or lid which is of eitherdouble thickness or spaced apart construction thereby providing a lcom--partment in the lid and it is further obvious that there has beenprovided a lconstruction which accomplishes the objects initially setforth.
